N. Y., A CORPORATION OF NEW YORK APPARATUS FOR COATING PIPES Application filed July 17, 1829. Serial No. 379,002.

This invention relates to an improved a paratus for coating pipe and has particular y to do'wit'h .the coating of large pipe such as employed in underground mains.

The-object of the invention is to provide a convenient and efficient-means whereby the outside of the pipe is conveniently covered or coated .with a water roofing composition such 'as bitumen, asphaltum, or compositions which are a plied hot and which cooland form a comp ete coating or covering for pipe that will protect the same from injurious contact with the ground.

In laying pipe lines, and particularly those underground, it is a slow, laborious, more or less unsat sfactory method such as heretofore employed in coating thesepipes. They are coated unevenly and the work is laborious and not by any means satisfactory.

It is therefore the broad object of our improved apparatus to greatly Improve the operation and the results accomplished and save time and labor.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and ar-' in operation.

1, 1 represent base irons, which may be channels, as shown, and on which angle bars 2, 2 are ri idly secured. These angle bars 2, 2 receive olts 3 secured by nuts 4, and on these bolts between the pairs of angle bars 2, 2 rollers 5, 5 are mounted to'turn.

These rollers are preferabl' arran ed in pairs, and the pairs are space apart t e desired distance, and said rollers preferably have flanges 6 at their outer ends so that when a pipe 7 is positioned on the four rollers, as clearly indicated in' Figure 1, the flan es 6 will prevent longitudinal movement 0- the P P- One pair of bars 1, 1 support parallel upright frames 8, -8 having a bearing, sleeve 9 at their upper ends and supporting a shaft 10 having a crank arm 11 atits outer end.

A sprocket wheel 12 is "provided on the inner end of the shaft 10 and a sprocket chain 13 is passed around the sprocket wheel 12 and around sprocket wheels 14 fixed to turn with two of the rollers at one end of the apparatus, as clearly indicated in the drawings.- a

With the parts as illustrated and as-- suming that a pipe 7 is positioned on the rollers 5, the operation is as follows, reference being made to Figure 2 of the, drawings:

One workman pours from a can or other receptacle 15 a coating material 16 onto the upper portion of the pipe 7 as the latter is turned by the crank arm 11. 7 Another workman holds a sheet or pad of asbestos or other analogous material against the coated 'pipe so as to prevent an excessive flow of the coat- 'ing material and to insure the even distribution of the same over the surfaceof the i The workmen move longitudinally .o t e pipe throughout the coating op'erationso that when one portion of the ipe is completely coated they move longitudinally of the pipe to allow another apphcation of the material throu hout the circumference or exterior of the pipe and thus apply the material in a more or less spiral form.

While we refer to the pouring apparatus as a can or receptacle it is obvious it may take any other form which will allow the ma-' terial to flow while hot on to the pipe, and

we may use any suitable means for -insuringv a. proper spreading of the material and the escape of excessive material but we believe that a preferable application is such as above described, utilizing two workmen, one applying the liquid and the other causing it to spread evenly as the pipeisrevolved.

Various changes and alterations might be made in the general form of the parts described without departing from our invention and hence we do not limit ourselves to the precise details set forth but consider ourselves at liberty to make such changes'and alterations as fairly fall within the spirit and scope of the appended claims.

We claim:

1. An apparatus for facilitating the coating of pipe, comprising a pair of independent supports adapted to be positioned in longitudinal alinement, and a pair of pipe supporting rollers on each support adapted to receive and ermit rotary movement of a pipe remova ly mounted thereon, said rollers having flanges thereon preventing longitudinal movement of the pipe.

2. An apparatus for facilitating the coating of pipe, comprising a pair of independdent supports adapted to be positioned in longitudinal alinement, a pair of pipe supporting rollers on each support adapted to receive and permit rotary movement of a pipe removably mounted thereon, and means for positively turning at least one of said rollers to permit rotary movement of the pipe.

3. An apparatus for facilitating the coating of pipe, comprising a pair of independent supports adapted to be positioned in longitudinal alinement, a pair of pipe supporting rollers on each support adapted to receive and permit rota movement of a pipe removably mounte thereon, said rollers hav ing flanges thereon preventing longitudinal movement of the pipe, and means for positively turning at least one of said rollers to permit rotary movement of the i HUGH M.
